Drained the gearbox last night, and I'm not entirely sure what the oil is trying to tell me.

The oil was dark grey, almost black, and opaque, not quite unlike the engine oil out of a diesel engine with a very slight contamination of coolant in the oil. The oil was cold when I drained the box, but it looked sort of "grainy" when it poured out, but it smelled like gear oil, no funny change of character.

Should I be OK just refilling it, and possibly change again in a few weeks, or is failure imminent? The colour of the oil suggests to me that some part of the box has been overheating badly, but I guess it could simply be age or that some material in the box wears off and turns black (like aluminium). It doesn't really sound very noisy, but then again I have had little road time with it.
